FIELD OF TECHNOLOGY

The following relates to a protective glove, and in particular to a structure and a manufacturing process of the protective glove.

BACKGROUND

Gloves are a common protective article, and wearing gloves may achieve good-looking and at the same time, protect the hands. According to different standards, the gloves may have different classification methods. According to materials, gloves may be classified into cotton gloves, woolen gloves, silk gloves, chemical fiber gloves, and composite material gloves; according to styles, gloves may be classified into long gloves, short gloves, single-finger gloves, and fingered gloves; according to usages, gloves may be classified into welding gloves, electric welding gloves, ritual gloves, ski gloves, space gloves, guard gloves, protective gloves, protecting gloves, working gloves, and boxing gloves; and according to functions, gloves may be classified into high-temperature resistant gloves, warming gloves, acid-alkaline resistant gloves, oil-proof gloves, grip gloves, welding gloves, and fire-resistant gloves.

The hands are one of the most sophisticated and delicate human parts. A hand is composed of 27 bones, and the bones of two hands account for ¼ of the total bones of a human body. Moreover, distributions and organizations of muscles, blood vessels, and nerves are tremendously complex. At a fingertip, the length of blood capillary in each square centimeter is several meters, and there are thousands of nerve endings. These delicate neural networks may enable us to be aware of cold, hot, or pain within several microseconds, and even may enable us to feel a vibration of an amplitude which is as small as a hair line. The hands keep moving since a person is born, and till the end of life, the hands may average 2.5 hundred million movements during a lifetime. However, we often ignore the importance of the hands, and do not protect the hands appropriately. As a result, among the industrial accidents causing incapacity, accidents of hand injuries are up to 20%.

In modern production operations, frontline workers operating a lot of devices such as a rock drill, a pneumatic pick, a pneumatic drill, an electric felling saw, and an electric impact drill tend to suffer from symptoms such as an injury to fingers, arm fatigue, and muscle soreness because of enduring vibrations of a machine which vibrates intensively for a long time. Being in such a working state for a long time will easily bring injuries to muscles or bones and occupational diseases. Therefore, the working condition for workers needs to improve, e.g., wearing professional protective gloves to alleviate muscular tone and fatigue, and reduce an injury probability.

At present, there are a lot of impact-resistant gloves. In Utility Model Patent No. 201420238981.9, an impact-resistant glove is proposed. An exterior surface of a front face of the glove is provided with a protective layer, and an internal surface of the front face of the glove is provided with impact-resistant cushions. The impact-resistant cushions are sponge impact-resistant cushions. The number of the sponge impact-resistant cushions is two, and the two sponge impact-resistant cushions are respectively located at a palm portion and a position at which the palm and fingers are connected. An exterior surface of a back face of the glove is provided with a protective cushion which is a quadrilateral rubber protective cushion. The quadrilateral rubber protective cushion includes a plurality of quadrilateral convex strips that are located at middle and upper portions of the quadrilateral rubber protective cushion. The exterior surface of the back face of the glove is further provided with five protective strips that are located at five finger portions, respectively. The protective strips include a plurality of protective bumps, where two ends of each protective bump are protective convex strips. However, the sponge impact-resistant cushions of the protective glove do not have obvious impact-resistant effects.

In another Utility Model Patent No. 201220130933.9, a shockproof, heat-resistant, cut-resistant, and wear-resistant glove is proposed. A layer of milled uneven rubber sheets is provided on a palm side of the glove. A plurality of convex bodies connected to each other is distributed on the rubber sheets. Internal of the convex bodies is filled with sponge-shaped air holes. The convex bodies are in a block shape or a section shape. The glove has a layer of uneven rubber sheets. Therefore, in actual use of the workers, it is difficult to bend the fingers and palm to make a fist. As a result, it is difficult to grip a tool or equipment tightly, which may cause an injury.

SUMMARY

An aspect relates to a protective glove which is mainly applied to industries such as factories, mines, and lumbering. The protective glove has good impact-resistant and anti-vibration effects; has relatively small influence on motions of a hand, for example, bending, making a fist, and stretching; and meanwhile, brings good feelings for gripping equipment or a tool.
